  New Revision: 33708

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=33708

  Log:
    * ext/dbm/extconf.rb: fix dbm_pagfno and dbm_dirfno detection with
      Berkeley DB.  Macro definitions needs arguments to detect correctly.
      SIZEOF_DSIZE needs -DDB_DBM_HSEARCH because db.h defines datum type
      only if DB_DBM_HSEARCH is defined.
